Register product serial numbers on the Juniper Networks website and update the installation base data if there is any
addition or change to the installation base or if the installation base is moved. Juniper Networks will not be held accountable
for not meeting the hardware replacement service-level agreement for products that do not have registered serial numbers
or accurate installation base data.

Update your install base at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp.
WARNING: Ensure that you understand how to prevent electrostatic discharge (ESD) damage. Attach
the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
Mount the EX2300
You can mount an EX2300 switch on a desk or a level surface, on two or four posts of a rack or cabinet, or on a wall. This
guide describes the procedure to mount the switch on two posts of a rack.
Mounting an EX2300 switch on a rack requires one person to lift the switch and a second person to install the mounting
screws.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the
building structure.
NOTE: When you mount multiple units on a rack, mount the heaviest unit at the bottom and mount the
other units from bottom to top in decreasing order of weight.
2. Align the mounting brackets along the front of the side panels of the chassis.
3. Attach the brackets to the chassis by using the mounting screws. Tighten the screws.
2
4. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket
holes with the threaded holes in the rack rail. Align the bottom hole in each mounting bracket with a hole in each rail,
making sure that the chassis is level.
5. Have the second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
Connect Power to the Switch

Connecting EX2300 to AC power
NOTE: Grounding is required for DC systems and recommended for AC systems. An AC-powered switch gets
additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using
the power cord.
To connect earth ground to a switch:
CAUTION: A licensed electrician must attach the lug to the grounding cable.
1. Secure the grounding lug on the grounding cable to the earthing terminal on the rear panel of the switch by using
washers and screws.
2. Connect the other end of the grounding cable to a proper earth ground.
To connect power to an AC-powered switch:
The power cord inlet is on the rear panel of the switch.
1. Squeeze the sides of the power cord retainer clip and insert the L-shaped ends of the wire clip into the holes in the
brackets above and below the power cord inlet.
2. Insert the coupler end of the power cord into the AC power cord inlet.
3
3. Push the cord into the slot in the adjustment nut of the power cord retainer. Turn the nut until it is snug against the
base of the coupler and the slot in the nut is turned 90° from the top of the switch.
4. If the power outlet has a power switch, set it to the OFF (0) position.
5. Insert power cord plug into the power source outlet.
6. If the power source outlet has a power switch, set it to the ON (|) position.
Connecting EX2300 to DC power
To connect power to a DC-powered switch:
The DC power inlet is on the rear panel of the switch. It has four terminals labeled INPUT1+, INPUT1–, INPUT2+, and
INPUT2–. The DC power inlet has a clear plastic cover.
WARNING: Ensure that the input circuit breaker is open so that the cable leads do not become active
while you are connecting DC power.
1. Grasp the cover in the middle, gently bend it outward, and pull it out. Save the cover.
2. Remove the screws on the terminals. Save the screws.
3. Connect the power cables to the power inlet by screwing the ring lugs attached to the cables to the appropriate
terminals (use the screws from the terminals).
•
To connect the switch to a single power source: Connect the positive of the power cable to the terminal INPUT1+
and the negative to the terminal INPUT1–. Connect the power cable to a power source.
•
To connect the switch to two power sources: Connect the positive of one power cable to terminal INPUT1+ and
the negative to the terminal INPUT1–. Then connect the positive of the second power cable to the terminal INPUT2+
and the negative to terminal INPUT2–. Connect each power cable to a power source.
4. Hook the plastic cover on one side of the terminal block and gently bend it inward to hook it on the other side also.
Step 2: Up and Running

Perform the Initial Configuration | 5

Perform the Initial Configuration
NOTE: To run the EZSetup script, the switch must have the factory-default configuration as the active
configuration. If you have configured anything on the switch and want to run EZSetup, you must revert the
switch to the factory-default configuration. See the EX Series documentation at
https://www.juniper.net/documentation/product/en_US/ex2300 for reverting the switch to the factory-default
configuration.
To connect and configure the switch from the management host:
1. Set the following values on the management host: baud rate—9600; flow control—none; data—8; parity—none; stop
bits—1; DCD state—disregard.
2. Connect the console port to the management host by using the Ethernet cable with an RJ-45 connector attached and
the RJ-45 to DB-9 serial port adapter.
NOTE: You can also use the mini-USB port to connect the switch to the management host (see the EX Series
documentation at https://www.juniper.net/documentation/product/en_US/ex2300).
3. At the Junos OS shell prompt root%, type ezsetup.
4. (Optional) Enter the hostname.
5. Enter the root password that you want to use for the switch. Reenter the root password when prompted.
6. Enable services such as SSH and Telnet.
NOTE: You will not be able to log in to the switch as the root user through Telnet. Root login is allowed only
through SSH.
7. Use the Management Options page to select the management scenario:
•
In-band Management—Use the automatically created VLAN, default, for management.
Select this option to configure all data interfaces as members of the default VLAN. Click Next. Specify the management
IP address and the default gateway.
•
Out-of-band Management—Configure the management port. Select this option to configure only the management
interface. Specify the IP address and default gateway for the management interface.
8. (Optional) Specify the SNMP read community, location, and contact to configure SNMP parameters.
5
9. (Optional) Specify the system date and time. Select the time zone from the list.
10. The configured parameters are displayed. Enter yes to commit the configuration. The configuration is committed as
the active configuration for the switch.
You can now log in by using the CLI to continue configuring the switch.

Safety Warnings Summary
This is a summary of safety warnings. For a complete list of warnings, including translations, see the EX Series documentation
at https://www.juniper.net/documentation/product/en_US/ex2300.
WARNING: Failure to observe these safety warnings can result in personal injury or death.
•
Permit only trained and qualified personnel to install or replace switch components.
•
Perform only the procedures described in this quick start and the EX Series documentation. Other services must be
performed only by authorized service personnel.
•
Before mounting the switch, read the planning instructions in the EX Series documentation to make sure that the site
meets power, environmental, and clearance requirements for the switch.
•
Before connecting the switch to a power source, read the installation instructions in the EX Series documentation.
•
If the rack has stabilizing devices, install them in the rack before mounting or servicing the switch in the rack.
•
Before installing or after removing an electrical component, always place it component-side up on an antistatic mat
placed on a flat, stable surface or in an antistatic bag.
6
•
Do not work on the switch or connect or disconnect cables during electrical storms.
•
Before working on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches.
Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the
terminals.
